Objective: To investigate and analyze the prevalence of dry eyes in Zhengzhou office workers, and identify the related risk factors in order to provide evidence for effective prevention and treatment. Methods: We selected 873 cases of Zhengzhou office workers who had checkup in our hospital from September 2019 to September 2020 as the research subjects. They were investigated with self-designed general information questionnaire and OCULUS Jenvis-OSDI dry eye questionnaire and scores of the questionnaires will be assessed. At the same time,they underwent dry-eye-related inspections such as slit lamp examination, corneal fluorescein staining score (FL), Schimier I test (SIT) and tear break-up time (BUT) assessment. The prevalence and risk factors of dry eyes in these office workers were statistically analyzed. Results: Among 873 Zhengzhou office workers, 360 cases were diagnosed as dry eyes, and the total prevalence of dry eye was 41.24%. The female prevalence rate was 44.62%, which was significantly higher than that of male (36.26%, P=0.014). OSDI scores and FL scores were positively correlation as well as BUT and SIT, while OSDI (and FL) and BUT (and SIT) were negatively correlation. Logistic multivariate analysis showed that dry eyes family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history were independent risk factors in office workers’ dry eye disease (all P<0.05), while drinking was protective factor (P=0.001). Conclusion: The dry eyes prevalence is high among office workers. The risk factors include dry eye family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history. We should strengthen the publicity and education of the dry eye prevention and treatment, provide eye health guidance, prevention and treatment according to different risk factors, and protect the office workers’ eye health.

Objective: To explore the causes of low vision after cataract surgery. Methods: Patients who underwent cataract surgery at Joint Shantou International Eye Center of Shantou University and the Chinese university of Hong Kong ( JSIEC) from October 2011 to March 2013, whose fundus status could not be seen before surgery, and the best corrected visual acuity <0.3 in the first week after surgery, underwent a series of detailed ocular examinations, including visual acuity, best corrected visual acuity, intraocular pressure, slit-lamp examination, fundus examination, fundus photography and optical coherence tomography. If no organic lesions of the retina were found, then visual evoked potential examination and visual field examination were performed. Two doctors analyzed the examination results of the examination, made the diagnosis of different fundus diseases, and statistically analyzed the causes of low vision after cataract surgery. Results: A total of 5 608 cataract surgeries were performed in our hospital from October 2011 to March 2013. A total of 49 patients (49 eyes) with best corrected visual acuity worse than 0.3 within postoperative 1 week 20 male and 29 female, 31 right eyes and 18 left eyes, aged (69.11±12.05) years on average. The proportion of low vision after cataract surgery was 0.87%. 12 cases (24.5%) of high myopic chorioretinopathy, 10 cases (20.4%) of ellipsoidal band defect, 8 cases (16.3%) of diabetic retinopathy, 5 cases (10.2%) of macular holes, 4 cases (8.1%) of age-related macular degeneration, 3 cases (6.1%) of macular epiretinal membrane, 1 case (2.0%) of thinning macular retinal thickness, 1 case (2.0%) of retinitis pigmentosa, 1 case of retinoschisis (2.0%), 1 case of branch retinal artery occlusion (2.0%), 1 case of Behcet’s disease (2.0%), and 1 case of ischemic optic neuropathy (2.0%), 1 case of epiretinal membrane (2.0%). Conclusion: Among patients with low vision after cataract surgery, high myopic chorioretinopathy accounts for 24.5%, followed by ellipsoidal band defect, diabetic retinopathy, macular hole, age-related macular degeneration, and macular epiretinal membrane. The use of optical coherence tomography can detect subtle microscopic retinal structural changes that affect vision after cataract surgery. For patients with visible fundus before cataract surgery, routine optical coherence tomography contributes to evaluating the prognosis of the operation, facilitating doctorpatient communication, and improving the degree of surgical satisfaction.

Abstract Objective: To discuss the change of corneal hysteresis and corneal resistance factor before and after laser in situkeratomileusis (LASIK), and to analyze their related factors by multivariate linear regression. Methods: In this prospective study, 70 eyes (38 patients) with myopia and myopic astigmatism undergoing LASIK were included. Related factors were measured preoperatively and at 6 months postoperatively by ocular response analyzer, noncontact tonometer (NCT), ultrasonic pachymeter, and Pentacam system. The correlation was analyzed between △CH, △CRF and preoperative and operative design’s parameters, and correlative factors analyze. △CH and △CRF were analyzed by the multiple linear regression. Results: CH before and after LASIK were (10.05±1.36) and (8.15±0.90) mmHg, and CRF before andafter LASIK were (9.91±1.38) and (6.92±0.88) mmHg. There was significant difference between preoperative and postoperative CH and CRF (P<0.01). △CH and △CRF were (1.90±1.15) and (2.99±1.23) mmHg. Preoperative CH, CRF, intraocular pressure (IOP), ablative depth (AD) and AD/CCT were positive correlated with △CH. Preoperative CH, CRF, IOP, AD, AD/CCT, preoperative spherical equivalent (SE) and predicted residual stromal bed’s thickness (RSBT) were correlated with △CRF. The regression equation of △CH and △CRF and influencing factors were △CH =?6.182 + 0.658CHpreoperative + 8.421AD/CCT (R2=0.639, P<0.01), △CRF =?0.007 + 0.725CRFpreoperative ? 0.014RSBT (R2=0.689, P<0.01). Conclusion: The change of CH before and after LASIK is correlative with AD/CCT. The change of CRF before and after LASIK is correlative with predicted residual stromal bed’s thickness. Ablative depth and predicted residual stromal bed’s thickness should be considered carefully during the surgical design.

随着科学技术的提高、手术方式的改进，角膜屈光手术成为治疗近视的主要方式。角膜屈光手术后角膜形态及生物力学的变化对于尽早发现术后相关并发症及术后长期稳定性具有重要意义，不同的术式及术后不同的恢复阶段角膜表面非球面参数及生物力学指标的变化存在一定差异，明确其变化的原因及机制可对临床研究提供一定的参考。

With the improvement of science and technology and the improvement of surgical methods, corneal refractive surgery has become the main way to treat myopia. The changes of corneal morphology and biomechanics after corneal refractive surgery are of great significance for early detection of postoperative complications and also affect the long-term stability after corneal refractive surgery. There are some differences in the changes of aspheric parameters and biomechanical properties in different surgical procedures and different postoperative recovery stages. Clarifying the reasons and mechanisms of these changes can provide some reference for clinical research.

纳入126名中山大学临床医学五年制4年级学生，对其接受为期1周的直接检眼镜见习教学后，进行问卷调查，了解学生对直接检眼镜学教学的看法以及学习过程中的操作难点。结果显示大部分学生认为直接检眼镜对临床工作有重要作用。但学生普遍反映学习过程难度大，师生视野无法共享，进而阻碍了师生直接的教学沟通。多数学生愿意接受更进一步的直接检眼镜教学。

A total of 126 senior of 5-year clinical medicine students in Sun Yat-sen University were recruited. After 1-week internship and direct ophthalmoscope training, a questionnaire survey was conducted to scrutinize students’ feedback about the training methods and learning difficulties during the internship. The results showed that most students thought that the direct ophthalmoscope played an important role in clinical work. However, students generally felt complicated and hard during the learning process due to the communication obstacle between teachers and students caused by the unavailability of vision sharing. In spite of this, most students are still willing to accept further direct ophthalmoscopy training.
